Citation check
Citation check: takes a claim and a cited source (URL or DOI) and returns supported, contradicted or not_addressed with the verbatim passage as evidence. The source is fetched with a full browser render. Dead, paywalled or PDF-only sources return source_unavailable, never a false contradicted.
